Subject[PATCH 3.16 110/366] IB/isert: fix T10-pi check mask setting
3.16.61-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Max Gurtovoy <maxg@mellanox.com>

commit 0e12af84cdd3056460f928adc164f9e87f4b303b upstream.

A copy/paste bug (probably) caused setting of an app_tag check mask
in case where a ref_tag check was needed.

Fixes: 38a2d0d429f1 ("IB/isert: convert to the generic RDMA READ/WRITE API")
Fixes: 9e961ae73c2c ("IB/isert: Support T10-PI protected transactions")
